CS5012A-BL7Z

Analog To Digital Converters (ADC) Overview

The CS5012A-BL7Z is a 12-bit monolithic analog-to-digital converter (ADC) manufactured by Cirrus Logic. It utilizes a successive approximation architecture with inherent track-and-hold functionality and unique self-calibration circuitry to maintain accuracy over time and temperature. The device supports both parallel and serial output interfaces and features digitally selectable unipolar or bipolar input ranges. Key electrical specifications include a conversion time of 7.2 µs, a maximum throughput rate of 100 kSps, and a linearity error of ±0.001% FS. Power consumption is specified at 150 mW under standard operating conditions.

Analog To Digital Converters (ADC) Feature Summary

• Self-calibrating architecture ensures excellent linearity and differential nonlinearity with no missing codes.
• Inherent track-and-hold input using a fast-slewing on-chip buffer amplifier.
• Microprocessor-compatible interface supporting parallel and serial data output modes.
• Digitally selectable unipolar and bipolar analog input ranges.

Analog To Digital Converters (ADC) Applications

• High-precision industrial data acquisition systems
• Process control instrumentation requiring stable long-term accuracy
• Test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BL7Z against manufacturer documentation to confirm tape and reel packaging configuration. Ensure power supply requirements match the specified ±5V analog and digital rails for optimal performance. Confirm that the -40°C to +85°C temperature range aligns with the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5012A when 12-bit resolution and high-speed conversion (up to 100 kSps) are required. Choose this component over the CS5014 or CS5016 if lower power dissipation (150 mW vs. higher for 14/16-bit variants) and faster throughput are prioritized over higher bit depth. Ensure the system can accommodate the necessary calibration cycle duration upon reset.

Analog To Digital Converters (ADC) Part Context

The CS5012A is part of the CS5012A/CS5014/CS5016 family of self-calibrating A/D converters from Cirrus Logic. These devices share pin compatibility and architectural similarities, differing primarily in resolution (12, 14, and 16 bits respectively) and corresponding conversion times. The family is designed for applications demanding high precision without external calibration components.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the CS5014 (14-bit) and CS5016 (16-bit). Note that these variants have different conversion times, throughput rates, and power dissipation characteristics compared to the CS5012A.
